IMPROVEMENT IN BARS FO R HORSESHOE-BLANKS.

Specification forming part of Letters Patent No. 166,238, dated August3, 1875; application filed J une 15, 1875.

the shoe as it comes from the said dies, the, V removal of which fin inthe completion of the shoe is a constant source of expense, trouble, andloss. Moreover the acute four corners of the hereinbefore-named ordinaryblank do not yield readily in the fitting of the blank to the peculiarcurves of the dies employed in the fabrication of the most approvedpatterns, and hence a'greater application of power in operating the diesis required, or a less perfectlyshaped shoe is formed than would be thecase if the blank was of a character readily fitting to the section ofthe dies, and avoiding the projection of a surplus quantity of metalupon the edges of the shoe as just set forth.

My invention is designed to provide a blank in which the objectionsreferred to shall be wholly obviated, and from which a perfect horseshoemay be turned by the easy working of the dies. To this end my inventionconsists in a horseshoe-blank, more or less diamondshaped in its crosssection, and with one of its longitudinal corners rounded, so that incross-section one of the sides of the blank shall pass into that nextadjoining on a curve or are, the blank as thus made fully securing theobject and results desired.

Figure 1 is a perspective View of a horseshoe-blank made according to myinvention, and Fig. 2 is a cross-section of the same. Fig. 3 is aperspective view of a horseshoe made from my improved blank, showing theshoe as it comes from the dies, and illustrating the advantageousresults arising from my said invention.

The blank is of any requisite kind or quality of iron, and drawn to theproper cross-section, herein presently fully described, by any ordinaryor suitable rolling-machinery. The iron may be first formed into longrods, having the required diameter and shape in transversecross-section, the rods being then divided into blanks, either cut offautomatically in the horseshoe-machine, to which the rod may be fed, andin which it may be severed, by suitable mechanism, or, in lieu of this,the rod may be cut into lengths, each suitable for the production of ahorseshoe, and these lengths, constituting the blanks, may be fed singlyinto the horseshoe-machine in any usual or suitable way.

The blank in its cross-section, with the exception of the longitudinalcorner a, is more or less diamond shaped. For example, the two oppositelongitudinal corners b are acute angles, while of the two remainingcorners c is an obtuse angle, and a would also be ob- I tuse if its twoadjoining plane surfaces were carried to the extent of joining with eachother, but the said corner, instead of being brought to an angle, isrounded, as fully represented in the drawings, thus, in connection withthe more or less diamond shape in crosssection, hereinbefore described,giving a novel and peculiar form and construction to theblank. When theblank as thus made is fed into and subjected to the action of theshaping-dies of a horseshoe-machine the oblique position of the sides ofthe blank permit it to adjust itself readily to the curvatures in thesurfaces of the dies, and thereby especially to give the inward bevel,shown at a b, in Fig. 3, which bevel is requisite to the most perfectshaping of the shoe. Simultaneous with this, the rounded corner, beingsituate at what forms the upper inner edge of the shoe, by its form,permits the spreading of the metal of the adjacent sides of the blanksufficient to prevent the formation of any appreciable fin upon theouter upper edge of the shoe, and also sufficient to permit the fillingof the dies at the said corner, the metal being brought thereat to amore or less squarely-defined corner, but without the projection of anymetal to form a fin. The metal that with an ordinary blank would besqueezed out to form fins upon the shoe as it comes from the dies, beingby my invention, brought into the space provided by the rounded corner;a, a, 1 1 d sl1aped1 a, 'subspanbia lly aeand fer the pnpp os e heI -Iein t0 f0r-m, witfl 0u l1 Projections, the. conresponds- 'se't fqnth. ingedge of the horseshoe.
